Hi guys. I've got a 600-size, 4-blade head that comes stock in gray/silver. I want to paint it flat black. I am not terribly well versed in painting, so I could use some tips.

Can I simply tear the head down to the hub and grips, hit it with a coat of primer and then paint it? Do I lightly sand it first? Am I missing some steps? Any help would be appreciated. Thanks guys.

I would leave it assembled to paint it flat black. Clean the areas to be painted with wax and grease remover. Scuff the head up with a scotchbrite pad. Tape off or remove the control balls. Give it a few light coats of flat black with time to dry between(20 minutes).

I would add one step to that: Use automotive grade self etching primer so it sticks to the aluminum better. You can get it at any auto parts store.

I lightly sand with a scotchbrite pad then put some oil on the bearing ares and add some tape to the rest. BBQ paint works best! Krylon Rattle can ..

Interesting that no one seems to disassemble the head down to the hub and grips and paint them separately. I thought for sure that'd be the best way to go. I'm kind of afraid of painting it assembled for fear of getting paint in or too near the bearings and any other areas that need to move freely/smoothly. I really don't want to gunk anything up...

I guess it just boils down to personal preference. I completely disassemble my heads prior to paint. I think the finished product looks better that way. Plus it gives me an opportunity to inspect, lube and locktite the assembly when I put it back together.
